Design and Realization of Integrated Management System for Data Interoperability between Point-of-Care Testing Equipment and Hospital Information System / 대한의료정보학회지

OBJECTIVES: The purpose of this study was to design an integrated data management system based on the POCT1-A2, LIS2-A, LIS2-A2, and HL7 standard to ensure data interoperability between mobile equipment, such as point-of-care testing equipment and the existing hospital data system, its efficiency was also evaluated. METHODS: The method of this study was intended to design and realize a data management system which would provide a solution for the problems that occur when point-of-care testing equipment is introduced to existing hospital data, after classifying such problems into connectivity, integration, and interoperability. This study also checked if the data management system plays a sufficient role as a bridge between the point-of-care testing equipment and the hospital information system through connection persistence and reliability testing, as well as data integration and interoperability testing. RESULTS: In comparison with the existing system, the data management system facilitated integration by improving the result receiving time, improving the collection rate, and by enabling the integration of disparate types of data into a single system. And it was found out that we can solve the problems related to connectivity, integration and interoperability through generating the message in standardized types. CONCLUSIONS: It is expected that the proposed data management system, which is designed to improve the integration point-of-care testing equipment with existing systems, will establish a solid foundation on which better medical service may be provided by hospitals by improving the quality of patient service.

Bone Mineral Density in patients with Intertrochanteric Fracture of the Femur / 대한정형외과학회잡지

The bone mineral density (BMD) has been measured for evaluation of the osteoporosis. Of the various methods of measuring the BMD, dual energy X-ray absorptiometry (DEXA) has been known to be an accurate, objective, and easily reproducible method. The authors measured BMD in patients with intertrochanteric fracture of the femur for comparison with results in the normal control. The BMD was measured in thirty-two patients with intertrochanteric fracture by dual energy X-ray absorptiometry from March 1993 to March 1995. And the relationship between the severity of osteoporosis and intertrochanteric fracture of the femur was studied. The comparison of BMD between fracture patients and normal control was done in the population below 79 years old of age (23 fracture patients and 90 normal controls). The average BMD in the intertrochanteric fracture group was 0.558g/cm2 in the neck, 0.425g/cm2 in Ward's triangle and 0.568g/cm2 in the trochanter, while in the normal control group it was 0.870g/cm2 in the neck, 0.681g/cm2 in Ward s triangle and 0.772g/cm2 in the trochanter. In comparison with the normal control group, the BMD in fracture group was about 79% of the normal control group. The BMD in the proximal femur was decreased by about 14% with the age increasing decennially after 50 years. The BMD at Ward s triangle and trochanter was much lower in type III and IV of Tronzo classification than in type I and II .The BMD did not show significant correlation with the height and weight of the patients.

Multisegmental Osteotomy for Kyphotic Deformity in Ankylosing Spondylitis / 대한정형외과학회잡지

Refractory deformity in ankylosing spondylitis is caused by loss of normal lordotic curvature in lumbar spine. For the correction of deformity, monosegmental osteotomy, intracorporal decancellation and multisegmental osteotomy are used. Among them, multisegmental osteotomy is reported to be safe because of its small correction amount at each level. Since 1989, authors treated 5 cases of ankylosing spondylitis with severe kyphotic deformity by multisegmental osteotomy and transpedicular instrumentation. All were young males between 22 and 35 years of age. Preoperative kyphotic deformity was 80°, 105°, 72°, 35°, 55° (Av. 70°) and amount of correction was 55°, 105°, 72°, 20°, 40° (Av. 58°) respectively. Levels for osteotony were 4 to 8 segments and correction at a level was 5° to 13° (Av. 8.3°). Normal standing upright posture and vision for straight forward were obtained in all. Instrumentation was Zielke in three Cotrel-Dubousset in two. One case of Zielke instrumentation showed rod failure. However, all showed solid bony union without any loss of correction or pseudoarthrosis. From the above experience, multisegmental osteotomy for the treatment of kyphotic deformity in ankylosing spondylitis was believed to be a safe and effective method of treatment.

A 14 Cases of Recurrent Shoulder Dislocation Treated by Modified Bristow Operation / 대한정형외과학회잡지

A recurrent shoulder joint dislocation was performed on fourteen cases who were treated by modified Bristow operation from June, 1978 to April, 1981. and following results were obtained. 1. The age of initial dislocation varied from 13 years to 23 years of age with the average of 18. 6 years. 2. The age at operation varied from 20 years to 28 years of age with the average of 23 years. 3. The duration of recurrent dislocaticn varied from 2 years to 8 years with the average of 4.4 years. 4. The times of dislocation varied from 6 to 50 times with the average of 17.1 times. 5. The roentgenograms showed the Hill-Sachs' Iesion in 10cases (71.4%), subluxation in 4 cases (28.6%), and glenoid rim abnormality in 2 cases. 6. The operative findings were Bankart's lesion in II cases(78.6%), glenoid rim erosion in 2 case, and subscapularis laxity in 2 case. 7. The complication and recurrence were not observed in this period. 8. The average limitation of abduction and external rotation were 5. 7 and 12. 2 degree respectively.
